3、 AMP IC TAS5711
The TAS5711 is a 20-W, efficient, digital audio power amplifier for driving stereo bridge-tied
speakers. One serial data input allows processing of up to two discrete audio channels and seamless
integration to most digital audio processors and MPEG decoders. The device accepts a wide range of
input data and data rates. A fully programmable data path routes these channels to the internal speaker
drivers.
The TAS5711 is an I2S slave-only device receiving all clocks from external sources. The TAS5711
operates with a PWM carrier between 384-kHz switching rate and 352-KHz switching rate depending on
the input sample rate. Oversampling combined with a fourth-order noise shaper provides a flat noise floor
and excellent dynamic range from 20 Hz to 20 kHz.
